thx!
So for 1250$ you even get a complete cilinder with liner installed seems like a good upgrade when the stock cylinder is worn (at this pace with my riding in 20 years )

I found a part nr 81730038100 from ktm complete cilinder+piston kit costing 649€ (for stock 565cc parts)
I don't know if this is for piston+liner or if the cylinder itself is also included....
For only liner/piston it seems expensive, but if the cylinder itselfs is included it's a bargain!
I will start to save some money so I can buy some parts next winter before ktm decides to stop making/selling them for the bergs
The 570 is a keeper so I have to start hoarding parts before it is to late lol

I'm quite sure that the official kit includes the cylinder!

Here's an example that shows the parts in question, taken from the parts book: Ref.01 - CYLINDER AND PISTON CPL. - 81730038100 - MotocrossCenter: Dirt Bikes, Enduro & Supermoto Store

Note that for the 104mm bore, the engine cases have to be bored out! Not necessarily such a terrible thing, I don't know!, but it's more work and more costs.

And one would probably want to do some form of balancing?

(as we're on the subject, the stock cases can take a 102mm piston/cyl)

Shame no kit or the 06-08 FE550 or are we talking grenade time for the bottom end ?

I thought the cylinder was the only thing that have to get bored out for the 104 piston and different liner ofcourse if it includes engine cases boring out and it's non reverseable (meaning you can't go back to 565 cc wit other cylinder. )
I wouldn't do it even though I would llike to try 610 one day

590 is to small of a difference IMO to bother
It would be nice to have someone with a 610 kit /stock crank with high miles to see how everything holds up.
I can live with a rebuild every 150 hours but if the bearings can't even survive that it seems a bit crazy

Nice find that link thx

I'd think you can go back to a smaller bore no problem, or at least I can't imagine otherwise. Mounting and sealing surely isn't any different, just clearance. Although I don't know for sure!

PEI Mudder, maybe there's some useful info here: 650 '700' kit do it yourself thread.... ... although the 550's bottom end seems to be considered more delicate than the 650's? Maybe it's just the higher crank weight though ?

I Ride: FE 610 oh yea
Cases not bored yay, just have to relieve the joins in the cases and then the liner is a slip fit in the cases.

The NJ207 bearings survive in the ktm 690 engines just fine. The big end will survive too, but nothing will last if abused or starved of oil. These motors make enough oil pressure to float a plain big end.

Application of a Ti wrist pin will offset some weight (we now have a big block chev sized piston rolling around in there. +18% mass iirc.
Or add metal to the crank counterweight, but I dont think you sumo fellas liked big slow revving tractors.

F''k you all. Now I dream/plan of going 610 again... And later add the crank for 660.
It just makes no sense. Except that it does...
